FIG. 7 is a flowchart showing a wireless power network monitoring method according to an embodiment of the present invention. The wireless powernetwork monitoring method 700 shown inFIG. 7 may be implemented on a wireless powernetwork monitoring device 200 shown inFIG. 2 using the graphical user interface tabs described above with reference toFIGS. 4 to 6 . - In
step 702, the wireless powernetwork monitoring device 200 boots up. Duringstep 702, the modules and interfaces of the wireless powernetwork monitoring device 200 are initialized. - In
step 704, thehandshake module 228 of the wireless powernetwork monitoring device 200 performs a handshake with theenergy transmitter 110 of thewireless power network 100. During the handshake process, thehandshake module 228 interrogates theenergy transmitter 110 via theenergy transmitter interface 222 and determines parameters such as the data format, operational status, and communication protocols required to establish the connection with the energy transmitter and each individual energy receiver connected to it. - In
step 706, theformat conversion module 224 and thecontrol module 230 of the wireless powernetwork monitoring device 200 are initialized with the data format and control protocols of thewireless power network 100 to allow the wireless powernetwork monitoring device 200 to extract information from theenergy emitter 110 and to generate control signals to control the energy emitter and the energy receivers of thewireless power network 100. - In
step 708, the total number of receivers connected to the wireless power network is determined and set as N to allow the wireless powernetwork monitoring device 200 to increment through each of the energy receivers of thewireless power network 100. - In
step 710, thegraphical user interface 226 of the wireless powernetwork monitoring device 200 receives a user input indicating storage and encryption options selected by the user. The user useslocal drive switch 452, thecloud platform switch 454 and theencryption switch 456 of the data storage andencryption display 450 to input a selection of a storage device and encryption method. - In
step 712, thestorage module 240 allocates space for storing data on either thelocal storage device 242 of the wireless powernetwork monitoring device 200 or thecloud storage 244 and if selected, theencryption module 232 is activated. - In
step 714, a counter n for energy receivers is set to 1. - In
step 716, the nth energy receiver is selected. Instep 718, state information of the nth energy receiver is requested from theenergy transmitter 110 via theenergy transmitter interface 222. - In
step 718, the requested information is received and theformat conversion module 224 converts the format of the received state information. Instep 720, the received state information is stored in a database on either thelocal storage device 242 of the wireless powernetwork monitoring device 200 or thecloud storage 244 depending on the user selection made instep 710. - In
step 722, thegraphical user interface 226 of the wireless powernetwork monitoring device 200 generates a list of corrective actions. This list may be generated by comparing the state information with thresholds for example to determine if the battery level is below a threshold and in such a case the corrective action may be to steer the radiofrequency beam generated by the energy transmitter to the nth energy receiver. - In step 724, the graphical user interface is updated with the corrective actions and the received state information. The information may be displayed as shown in
FIG. 4 or one ofFIGS. 5 and 6 depending on the type of energy receiver device. - In
step 726, user commands are received though thegraphical user interface 226 of the wireless powernetwork monitoring device 200. The user may input the commands by selecting theselect buttons 444 shown inFIG. 4 . - In
step 728, thecontrol module 230 of the wirelessnetwork monitoring device 200 generates commands for the nth energy receiver based on the user commands received instep 726. These commands are sent to theenergy transmitter 110 though theenergy transmitter interface 222. In response to the commands, theenergy transmitter 110 either modifies its behavior or sends commands to the nth energy receiver. - In
step 730, the energy receiver counter n is incremented. Instep 732 it is determined whether the incremented value of n is greater than N. If the incremented value of n is less than N, then the method moves to step 716 and thesteps 716 to 728 are carried out for the next energy received. If the incremented value of n is N+1, then the method moves to step 714 and the value of n is reset to one and thesteps 716 to 728 are repeated for the first energy receiver. - In the examples described above, the wireless power network monitoring device monitors and controls a single wireless power network. In practice, multiple wireless power networks can be connected to wireless power network monitoring device. In this case, while the wireless power network monitoring device boots up, it handshakes with each of the energy transmitters connected to the wireless power network monitoring device.
